Ceramic metal definition.

Many ceramics contain a mixture of ionic and covalent bonds between atoms. In general ceramic fibers consist of both metallic and non metallic. Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics especially advanced ceramics are compounds of metallic elements and carbon nitrogen or sulfur.

Ceramic fibers such as al 2 o 3 and zro 2 used in composites are usually 3d isotropic polycrystalline material having covalent and ionic bonds 25. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications. A ceramic is an inorganic nonmetallic solid generally based on an oxide nitride boride or carbide that is fired at a high temperature. Most ceramic coatings are electrically nonconductive making them excellent insulators have a significantly higher level of abrasion resistance than most metals and are capable of maintaining their integrity under severely elevated temperatures.

Ceramic and materials engineers are the people who design the processes in which these products can be made create new types of ceramic products and find different uses for ceramic products in everyday life. Ceramic fibers belong to a wide category of materials which include clay minerals pure metal oxides oxide mixtures and glass. Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids. Ceramics may be glazed prior to firing to produce a coating that reduces porosity and has a smooth often colored surface.

Some elements such as carbon or silicon maybe considered ceramics ceramic materials are brittle hard strong in compression and weak in shearing and tension. Ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.
